Much of the rhetoric being bandied about so far seems to imply that Fox is acting in the interests of its cable and satellite distribution partners: By implementing TV Everywhere–type authentication for broadcast content online, it’s merely eliminating some of the friction that’s cropped up in its negotiation over retransmission fees. No one was happy that Fox was demanding more compensation for content that appeared on cable and satellite when, let’s face it, the network was essentially giving the same shows away for free on Fox.com and Hulu.

But adding authentication could also be a clever negotiating tactic as Fox seeks even higher fees from those distribution partners. Let’s say you’re Comcast, Time Warner Cable, DirecTV or any number of other major distributors that haven’t yet signed up for Fox’s mid-August launch of online authentication: Fox comes to you and says that it’s finally implemented a sign-in system that will ensure that only pay-TV or Hulu Plus subscribers will have access to its content the day after it airs online. But now that it has, it would like to get paid a little more in retrans fees, because, after all, it will be providing more value to your subscribers.

Do you pay up? Or do you risk disenfranchising your subscribers, who were once able to watch shows on Hulu the day after they’ve aired but can no longer do so because their cable provider isn’t a part of Fox’s exclusive next-day club?

And Fox is unlikely to be the only broadcast network to do so. Once it has proven the model that authentication equals more retrans money, you can expect CBS, ABC and NBC to jump on board as well, using next-day access to Hulu and network sites as an incentive to rework their deals with pay-TV providers.

The big loser in all of this will be consumers. They will not only be used as pawns in the next round of retrans fights but as a result will also lose access to a service they’ve been accustomed to getting for free. And as broadcasters use access to online video as a way to squeeze ever-higher retrans fees from distributors, those costs will eventually get passed on to subscribers in the form of higher cable bills.

Fox and other broadcasters might justify the introduction of TV Everywhere–type logins as just extending the existing cable model online. But at the end of the day, it seems “authentication” is just a fancy word for charging users more.
